Description
In this talk I present a new determination of the unpolarised fragmentation functions (FFs) for Lambda production from single-inclusive e+e- annihilation, semi-inclusive deep-inelastic scattering and pp collisions data. The analysis is done at both next-to-leading order (NLO) and next-to-next-to-leading order (NNLO). We extract the unpolarised FFs defining a parametrisation in terms of a neural network and determine their uncertainties with a Monte Carlo sampling method.
